  1. Detailed information

JDB-1 solid inlaid bearing, is on the base of brass. Inlaid graphite or MoS₂A high performance solid lubricant for solid lubricant. It breaks through the limitation that the general bearing depends on oil film lubrication. In the process of use, the friction heat of the solid lubrication and the axial friction, the excellent conditions for the formation of oil and powder, the protection of the shaft is not worn, and the solid lubrication is permanent. It is twice as hard as copper, and twice as high. At present, it is widely used in metallurgical continuous casting machines, such as railway stents, rolling equipment, mining machinery, ships, turbine, etc., such as high temperature, high load, low speed and heavy load etc.
